The research studies how outstanding teachers from Hong Kong conceptualize teacher success or effectiveness. This study adds to the knowledge base concerned by raising the importance of the coexistence of personal attributes and professional qualities as well as contextual factors, in bringing out the success of a teacher. It draws the attention of teacher educators/trainers and school administrators to the necessity of viewing the concept of teacher success from a broader perspective, instead of focusing narrowly on the professional qualities of a teacher. It also provides insights for school administrators in selecting teachers or supporting their work. 相似文献

This study statistically analyzes data from 756 evangelical and Latter-day Saint youth regarding their perceived in-class spiritual experiences of twenty items related to Christian theology. The data indicates similar spiritual outcomes between the two groups, with no statistically significant differences between eleven of the twenty spiritual experience items. However, evangelical participants most highly reported affective spiritual outcomes and least commonly reported action-oriented spiritual outcomes, while Latter-day Saint youth most highly reported action-oriented spiritual outcomes and least commonly reported cognitive spiritual outcomes. Action-oriented spiritual outcomes constitute the greatest difference between the two groups. We explore how the differences between evangelical and Latter-day Saint pedagogy and theology might account for these differences. 相似文献

In this paper we introduce the concept of a Prolog programming technique. This concept is then distinguished both from that of an algorithm and that of a programming cliché. We give examples and show how a knowledge of them can be useful in both programming environments and in teaching programming skills. The extraction of the various techniques is outlined. Finally, we discuss the problem of representing techniques where we conclude that the most promising approach is the development of a suitable meta-language. 相似文献

Thirty children with partial sight and 30 children with unimpaired sight aged between 8 and 12 years were randomly assigned to either verbal mediation or visual mediation training regimes. Participants were asked to complete four variations of the Tower of Hanoi puzzle and success on the task was judged on the basis of the number of moves and time taken to complete the puzzles. Children with visual impairments had some difficulty in adjusting to the requirements of the problem‐solving tasks. However, on the final and most difficult of the tasks (a four‐disc problem), the children with impaired sight performed very much like participants without visual impairments. The effect of verbal mediation training was superior to that of visual mediation training in the final trials of the four‐disc problem‐solving period for both children with partial sight and children without visual impairments. 相似文献

In this paper, thermal mixing characteristics of two miscible fluids in a T-shaped microchannel are investigated theoretically, experimentally, and numerically. Thermal mixing processes in a T-shaped microchannel are divided into two zones, consisting of a T-junction and a mixing channel. An analytical two-dimensional model was first built to describe the heat transfer processes in the mixing channel. In the experiments, de-ionized water was employed as the working fluid. Laser induced fluorescence method was used to measure the fluid temperature field in the microchannel. Different combinations of flow rate ratios were studied to investigate the thermal mixing characteristics in the microchannel. At the T-junction, thermal diffusion is found to be dominant in this area due to the striation in the temperature contours. In the mixing channel, heat transfer processes are found to be controlled by thermal diffusion and convection. Measured temperature profiles at the T-junction and mixing channel are compared with analytical model and numerical simulation, respectively. 相似文献

Distributed cooperative controller design considering guidance loop and impact angle 总被引:1,自引:0,他引:1
This paper presents an integrated distributed cooperative guidance and control scheme for multiple missiles to attack a single target simultaneously at desired impact angles. The scheme is divided into two parts: individual part and cooperative part. For the individual part, partial integrated guidance and control method is adopted to generate the elevator deflection (which is a realistic control input) to ensure that the missiles fly along their respective desired line of sight and hit the target; this is in contrast to previous works which analyze only the engagement dynamics and use missile accelerations as the control input, however, the proposed controller also considers the missile dynamics, thus enabling the implementation of an autopilot. For the cooperative part, using only information from adjacent missiles, the proposed distributed cooperative controller can make all missiles hit the target simultaneously. Hence in this scheme, each missile can hit the target at desired angles and at the same time, thus achieving salvo attack. Simulations are performed to verify the effectiveness of the scheme. 相似文献

With the rise of the situated cognition paradigm in cognitive science, cognitive apprenticeship has become increasingly prominent as a model of instruction. This paper critically reviews traditional approaches to learning and education to motivate the need for fresh ways of thinking about these topics. Cognitive apprenticeship as an approach to improving learning and education is described. We present an overview ofSmallTALKER, a learning environment for Smalltalk programming, and illustrate how the instructional methods of cognitive apprenticeship have been applied in developing that system. The paper concludes with a discussion of issues related to system development effort, evaluation, perceived limitations, and plans for related work. 相似文献

The Powerhouse Museum in Sydney, Australia houses the world's most significant and comprehensive collection of Speedo swimwear and accessories. The museum has identified a problem with the long-term storage of certain Spandex/Lycra® items where the elastane fibre has degraded leading to oil formation. Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) determined that most of these garments were manufactured using nylon-elastane fibres, and the elastane component comprises polyetherurethane or polyesterurethane polymers. Certain polyesterurethanes are known to be vulnerable to hydrolysis, and this was confirmed for a subset of the collection using two chemical testing protocols, and a thermal testing protocol that reproduced the oil formation. A polyetherurethane garment in the collection was unchanged by these tests. The oil from the thermal testing was confirmed as a breakdown product of the polyester component of the elastane fibre, using ATR-FTIR spectroscopy, X-ray photoelectron spectroscopy, and time-of-flight secondary ion mass spectrometry. The study demonstrates the value of ATR-FTIR for minimally invasive identification of elastane fabrics that may require specialized storage in a humidity-controlled environment. 相似文献
